To all 'whom it may concern.'

Be it known thaty I, Crmenes THOMAS MASON, a citizen of the UnitedStates, residing at Sumter, inthecounty oit Sumter and State of SouthCarolina, lhave invented certain new and useful lmproveinents in Thisinvention relates to a combined. coil and condenser for use in anelectrical dynamo and has for its objects the positioningof thecondenser nearer the primary Winding of the coil than has heretotorebeen accomplished, the support'of the condenser by the coil, and thecombination of the coil and condenser in such a manner that thecondenser is readily removed from the coil Without unsoldering anyconnections.

i For the sake of illustration l show the invention as usediiiconnection with an ignition dynamo or' the type shown iii my pending.application No. 14,409 oi i915, but is is obvious that saine may `beemployed in connection With any type of dynamo used for any purpose, inWhich a combined gen erating Winding and condenser may be advantageouslyemployed.

In ignition dynamos of the type shown in in the hereinbeiore mentionedapplicationi the field structure carrying the windings is movable aboutthe axis of the rotating polar extremities of the magnet for timingpurposes. This movable held structure is'provided with two upwardlyprojecting pole pieces across which is piaced a core carry ing thegenerating windings. necessary to use a condenser in the primary eircuitol such a dynamo and this condenser has heretofore been mounted vonsonic part of the machine framework, or in the cover of the breaker boxor interrupter. Considerable diiiicultyhas heretofore been encounterediii suitably associating the oondensei' directly with the iviriniarywinding, although such an arrangement is obviously much to be desired asit not only eliminates circuit connections, but also places thecondenser in a generator of the above-mentioned type up out of the Way,and directly connects same across the terminals ot the primary windingin a position to insure the most etlicient result. l

ln theaccompanying drawings, Figure l is a view partly in sectionshowing a mag neto embodying this invention. Fig. 2, a top view of thecombination coil and condenser structure. Fig. 3 is anl end view of Fig..2.' `Like figures of refeiencedenote the same parts Wherever they areshown.

-1 and 2 denote the pole pieces of a Iieldl structure movable about tlieshaft 3 for tim ing purposes. Connecting the top of said poles is thecore e provided With suitable heads 5 and 6, preferably ol insulating material. Between said heads and suitably at# tached thereto is the'insulating plate 7 upon which is mounted Contact sector 8 arranged toContact with a suitably iiXed terminal carried on the traine Work ot the.machine so that sector. 8 is always in engagement with said terminal asthe coil is moved when timing. T he arrangement of the sector and fixedterminal does not relate specilically to this invention, and are notshown here, but are fully described and claimed in my pendingapplication hereinbefore mentioned.

Mounted upon one of the heads of the coil is a suitable terminal 9 towhich one end of the primary winding is attached. The

Patented May Si, 1939?., i-

other end ot'tlie primary Winding is at-- that they connect to terminalS) and-core respectively, thereby electrically connect A the condenserdirectly across the terminals of the primary winding. It will also beobserved that the attaching means such vas the. screws ld and lt alsomechanically 'secure the condenser 'in place, so that it is securelyheld in position on the coil and moves there with. P

It will also be observed that the screw or other means le inalies ametallic connection from the condenser to the pole piece l and to `themetallic body or frame Work oit the generator thereby electricallyvconnecting one side ot the primary and condenser to the grounded side otthe circuit interruptor mechanism. rllhe insulated contact oi? theinterrupter is connected in any suitable inanner to terminal 9, arealready known, as is also the operation of a machine o't thisdescription, do not describe same here. Y

From the foregoing description the advantages of my invention will beapparent As such arrangeinents ,sten 'ally as desorihed.
